ORCHARD OIL-BURNER.

Specification of Letters Patent.

Patented Feb 13, 1912.

Application filed August 8, 1910. Serial No. 576,223.

To all whom it may concern:

Be it known that I, GEORGE C. RICHARD- SON, a citizen of the United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented certain new and useful Improvements in Orchard Oil-Burners, of which the following is a specification.

This invention relates to orchard oil burners of that type employed chiefly for the protection of orchards by the wide dissemination of heat and enveloping smudge in the atmosphere immediately enveloping the trees of an orchard and my object is to produce a burner of this type which performs its function efliciently and reliably and embodies the desirable features of simplicity, strength durability and cheapness of construction.

With this object in view and others as hereinafter appear, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings: in which Figure 1, is a plan view of an orchard oil burner embodying my invention. Fig. 2, is a side view of the same. Fig. 3, is an enlarged sect-ion on the line IIIIII of Fig. 1.

In the said drawings, 1 indicates a supply tank of any desired capacity preferably having a filling opening not shown, closed by a plug 2, and provided near its bottom wlth an opening 3 in which is secured the lower end of an inclined discharge pipe controlled by a valve 5, of the type shown or any other suitable or preferred type.

6 indicates a burner, the same being preferably of cylindrical form and consisting of a bottom 7 and a wall 8, provided with perforations 9 to admit air to support combustion in the burner, and said burner is provided with an opening 10, receiving the contracted or neck portion 11 of a funnel 12, the body of the funnel being arranged within the burner and the contracted neck portion receiving the discharge or higher end of the oil supply pipe 4.

In practice this burner is arranged at the desired point and the valve is opened to permit a small quantity of oil to flow through the pipe into the burner where it is ignited, the valve being so adjusted that I the oil is consumed in the burner as rapidly as it is supplied thereto air entering through the perforated wall and supplying suflicient oxygen to support combustion, the oil being preferably of that type which in burning generates intense heat and a heavy smoke or smudge which rises slowly out of the upper end of the burner and is disseminated widely through and around the trees of the orchard so as to completely envelop the same and constitute a blanket above the trees which protects them from injury by frost.

I have found from experience that the burner operates more efliciently by inclining the supply pipe upwardly toward the burner so that any gas generated in the latter will not have the eifect of arresting or checking the flow of oil as such gas entering said pipe will overlie the oil therein and thus permit the same to flow uninterruptedly into the burner, the dotted lines in the pipe, Fig. 3, indicating the level of the oil. I have also found that by providing the discharge end of the pipe within the burner with a flaring end that the oil is given a greater opportunity to spread and enter the burner in a thin film and that the said flaring end furthermore, being subjected to the action of the flame is raised to a high temperature and tends to vaporize the oil before it reaches the bottom of the burner and as a result the latter operates with greater efficiency and the elements thereof which would otherwise be slow to burn are so eifectually consumed that there is no material accumulation of residuum on the bottom of the burner which would in a short time impair its efliciency and necessitate frequent cleaning of the burner.

From the above description it will be apparent that I have produced an orchard burner embodying the features of advantage enumerated as desirable and I wish it to be understood that I do not desire to be restricted to the exact details of construction shown and described but reserve the right to make changes properly falling within the spirit and scope of the appended claim.

Having thus described the invention what I claim as new and desire to secure by Letters Patent, is

An orchard burner, comprising a burner having an imperforate bottom and an annular wall extending upwardly from the margin of the bottom and provided with perforations, an oil supply tank, a feed pipe extending from the supply tank at one side thereof to the burner at one side thereof and communicating with the latter in a plane above the plane of the point of communication with the supply tank and provided within the burner with aflared end, all points of the bottom of the feed pipe between the tank and burner lying above the plane of said bottom of said pipe at its point of communication with the supply tank, and a valve controlling said feed pipe. 10 In testimony whereof I aflix my signature in the presence of two witnesses.
